Can't wait to see what you come up with, I know it will be Crazy, lol.
The chain is still off, cause I still remember when I put the Cag carb piston in backwards which raises the piston way up. When I started the MT-A1 it tried to take off, i ended up holding it in air with my left hand and find the kill button on the handle bars with my right, almost wet my pants, lol. I just want to run the engine a few times to get it ready to rock & roll.
It has a new ring, flywheel, coil, reed plate and totally rebuilt Polini clutch w/ Socchi springs and bolts & nuts. think the sprockets are 6/66, 11 to 1, might make it 9.5 to 10 to 1. Want to start painting the body next week when it will be 75 degrees. Have a new C1 windshield going to cut it to fit the fairing. Also have two C1 double brake levers here if needed, have to find another caliper and disc.
My avatar GRC GP is going on the kitchen table tomorrow after I fix the gas lines. The rebuilt 40cc BZM racing engine still has no water pump, but its ready to run. I have a billet BZM pump here, also have an electric pump w/ switch and LiLon 8,000 Amp hr. 12v. rechargeable battery. Not much room in this small all alum frame. Think I found a place behind and below the billet BZM clutch housing off the frame is an un-drilled tab I can mount the pump bracket to, so the pump pulley will be pulled not pushed.
Another problem if I put a pump pulley behind the front pinion gear on the BZM the chain will not line up w/ the rear sprocket. The 690 cases and billet clutch housing mounts are 2mm bigger so I can't use my Polini 80mm bell housing with pulley. The bell has a different nose for the pulley drive versions.
